Ronda Rousey finished her fight with Sarah Kaufman by arm bar in just 54-seconds tonight because she had to get to her next media appearance. Rousey moves to 6-0 with six first round submissions by arm bar. Immediately after the win, Rousey went to work challenging Cris “Cyborg” Santos to come down and meet her at 135 pounds. The Rousey Hype Train will now continue chugging until she grabs another woman’s arm on Showtime.
